Re: Position idlers to get better chain wrap -- a question about good practices.

In 2007 we had an two 10 tooth sprockets stacked vertically with about 3/8" clearance between them. We had no problems with it at all. The chain was coming in about 30 degrees off horizontal from each side (30 degrees towards the side that gave it more wrap).

Hope that helps. The mentor who designed it with us was from 687 and he had build a lot chain driven robots in the past and I believe he said as long as there is room for the chain to go trough, there won't be problems.
